Network Architecture and Performance

ETSN10, 7,5 credits, A (Second Cycle)

General Information

Main field: Communication Systems. Compulsory for: MWIR1Elective for: C4-ks, D4-ks, E4-ks, I4, I4-pvsLanguage of instruction: The course will be given in English

Aim

The course gives a deep understanding of the principles of
network construction from a performance aspect. The course
comprises two main components, investigation and dimensioning of
networks through mathematical modelling and simulation as well as
fundamental network architecture types. The course covers both
public and local access network constructs such as 3G/LTE as well
as WLAN, Ad-Hoc and Mesh networks, Internet of Things, etc.
Furthermore, the course covers performance issues such as queuing
behaviour, congestion control and performance engineering. The
course covers both theoretical aspects through modelling as well as
practical studies through a system design project.

Contents

The course gives a deep understanding of principles, functions
and techniques that form the foundation of communication networks
with an emphasis on wireless communication systems. In particular,
the course covers these functions' behaviour and performance based
on the stochastic nature of the data streams in modern
communication networks.

The course covers both public systems (3G, LTE) and technologies
for wireless local networks (WLAN, Ad-Hoc, and mesh networks). The
course gives an understanding of how these systems integrate more
and more, advantages and disadvantages as well as problems and
their solutions in connection with this integration. The courses
also discusses current and future trends in network systems such as
Internet of Things and Tactile Internet, and the enabling
technologies being developed for them.

The course structure contains lectures and exercises, as well as
a lab on network simulation and data analysis. Further, students
will complete a group-based system design project.

Examination details

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)Assessment: The course assessment is divided in two sections, a written exam and a project assignment. The grade of the course is based on the written exam.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
